What warfarin side effects should you watch for?
When you take warfarin, your blood won't clot as easily. If you accidentally cut yourself while taking warfarin, you may bleed heavily. However, the risk of a major bleeding event is low.
You're more likely to have bleeding problems if you're older than 75 or take other blood-thinning medications that can further increase your bleeding risk.
You're also at higher risk of bleeding problems if you have:
- Uncontrolled blood pressure
- A history of stroke
- Stomach ulcers, gastritis or peptic disease
- Kidney problems
- Cancer
- Alcoholism
- Liver disease
- Increased risk of falls
Some studies suggest that bleeding problems are more likely to occur during the first month of taking warfarin rather than later in treatment.
